SPECIFICATION forming part of Letters Patent No. 376,782, dated January 24, 1888.

Application filed-September 12, 1884. Serial No. 142,8713. (No model.) 7

To all whom it'mag] concern:

Be it known that I, THOMAS W. McFAR- LAND, a citizen of the United States, residing in Chicago, county of Cook, and State of Illinois, have invented a certain new and useful Improvement in Sad-Iron Heaters,-of which the following is a specification.

This invention relates to an improvement in sad-iron heaters of that class inwhich the heat-l IO ing apparatus has consisted of a stove or heater constructed with a central polygonal drum, a surroundingjacket provided with slots extending downwardly from its top to form passages for the handles of the irons, which are introduced between the drum and the jacket when it is desired to heat them, and aseries of lids hinged to the top of the structure and provided for respectively covering a series of compartments into which the annular space between the drum and its surroundingjacket is divided,

so as to form a separate heating-chamber for each sad-iron. L The objects of my invention are'to improve the construction of a heater of such character in several particulars, so as to render it easier of manufacture, more readily taken apart and put together, stronger, more durable, and more efficient than heretofore, and to provide certain self-adjusting or yielding joints between 0 certain of its members,in order to compensate for the unequal degrees of lateral or diametrical'and longitudinal expansion and contraction between the heating-drum and the walls of its surrounding chambers, it being found thatin 3 5 heaters of, such character as heretofore constructed with rigid and unyieldingjoints the unequal degrees of expansion between its mem bers break and tear the parts at the joints, thus necessitating the removal of the injured 40 parts and theirreplacement by others, which obviously is troublesome, aswell as an expensive afl'air. These objects I attain by the devices illustrated in theannexed drawings, in

which- Figure 1 represents a perspective of a sadiron heater embodying my invention; Fig. 2,

a top plan view of the same with the top cov-i ering and pyramidal base removed; Fig. 3, a

coupling-bars joined together, the dotted lines 7 indicating the drum' and illustrating the manner of coupling together the jacket and said 7 drums; Fig. 5, an enlarged detail planview illustrating the connection of the compartment-covers with the two-part ring; Fig. 6, an enlarged detail vertical section on the line a: ayFig. 5,'for more clearly illustrating the configuration of the two-part ring and its connection with drum and covers.

Referring by letter to the several figures of the annexed drawings, in which like letters denote like parts, A indicates a vertically-arranged drum within which'thev fire is tobe made. This drum is provided at its base with a grate, B, the construction of which is, by preference, that of a rotary grate arranged'to turn on a supporting-bar, B, which is'upheld .at its ends by means ofa flange or lugs formed with the base end of the drum. n

The base-support O for the dfum is of any construction suitable for upholding the drum and for providing an ash-pit, to which access can behad by opening a door, O, with which 7 the base-support is-furnished. The polygonal drum'is surrounded by a jacket, so as to form a space between the two for the sad-irons,

which are to be heated, anda series of verti-- cal slots,D,are formed in this jacket,con1nienc- 8o ing at the top and extending down to a point near the base thereof, in order to provide passages for the handles of the sadirons when the latter are introducedat the upper portion of the space between the jacket and the drum, .8 5

sothat they can be let down with their faces againstthe sidesof the drum. v The annular space between the jacket and the drum is also divided into a number of compartments, E, corresponding to the number of- 0 e sides of the polygonal drum, each compart- 'ment being designed for the reception of a;

single iron. V p, v, The jacket is composed'of a number of-sections, F, which are arranged to form a con- 5 tinuous jacket around the drum. The slots or passages D forthe'handles of the sad-irons occur between the opposing edges of these sections of which the jacket is composed,

and as a convenient way of formingthe said 10o" slots alternate sections are provided with oblong notches along their side edges, whereby section is bolted or riveted to a flange, F,

formed along the outer vertical edge of a partition, as illustrated in dotted lines, Fig. 4. The partitions which are thus'connected with the jacket-sections are detachably connected with the drum by means of sliding or yielding joints, which serve to admit of different de grees of longitudinal expansion of the drum and of the partitions without endangering the breakage of the connections between them, it being evident that the end or longitudinal ex pansion and subsequent contraction of the drum will be far in excess of that of the surrounding partitions and jacket-sections. To such end each partition is secured at its top edge to a bar, G, havingan outer T-shaped end secured to the partition, and having its inner end adapted to form a coupling, G extending back from the inner vertical edge of the partition.

The inner coupling ends of the bars G are v adapted to fit in vertical slots A in the top end portion of the drum and to embrace both the inner and outer sides of the latter, for which purpose the coupling is in the nature of two pairs of flanges or ears formed at an end of a flat bar and adapted to the configuration of the drum.

The slots or notches A are formed in the upper ends of the drum at the angles thereof, and the couplings are connected with the drum by passing down into the notches or slots in the drum, the middle or neck portions of the couplings formed between the pairs of cars or lateral projections at theinner ends ofthe bars, as illustrated in Fig. 4, in which a portion of the drum and one of the slots thereofis shown in dotted lines. The couplings are thus free to move up and down in the slots, so as to be susceptible of a self-adj ustment in case of any variation in the degree of longitudinal or vertical expansion or contraction between the drum and any or all of the partitions between the drum and any one of the partitions and the jacket-section attached to the latter. In this way I provide a yielding connection which will serve to compensate for any difierence in the degrees of end or vertical expansion between the main elements composing the body portion of the heater, thereby avoiding breakage, and that it will also admit of the parts being readily taken apart or fitted together.

The rest H for the sad-irons, when thelatter are placed within the chambers in order to be heated, consists of an annular disk, constituting a bottom for the several compartments around the drum. This annular disk is provided along its outer edge with a flange, H, which is bolted to the inner sides of the jacketsections. The partitions simply rest at their lower ends upon this annular disk, which slopes downwardly toward the center, so as to adapt it to conform to the several angular ends of a sad-iron. The annular disk, which is thus provided as a'snpport or rest for the sad-irons and as a bottom for the heating-chambers, has at its inner edge a sliding or yielding connection with the drum, whereby the diametrical or lateral expansion and contraction of the drum in excess of that of the surrounding members'shall be permitted to take place without injury to its connection with the latter. To such end the drum is provided near its base end with an external seat, A", which is provided with slots A radial to the drum, and preferably made in the nature of a ledge extending continuously around the drum.

The inner edge portion of the annular disk Hrests upon this seat A", and is provided with bolts H,passing through the slots in the seat, thereby affording a yielding connection be tween the drum and the bottom of the compartments to which the jacket sections areconnected.

It will be obvious that this bolt-andslot joint between the disk and the drum could be attained by slottingthe disk in place of slotting the ledge, as herein shown.

For each heating-compartment E, Iprovide a hinged lid, I, to allow the compartment to be opened or closed, as may be required. These lids, constituting an annular series at the top of the heater, are hinged to a two-part ring which is seated upon and bolted to the top edge of the drum. The lower half, K, of the said ring is seated upon the top edge of the'drum and upon perforated lugs or cars A, formed at intervals along the top edge of the drum, and said part of the ring is also pro vided with an annular flange, K, which fits against the outer side of the drum. This outer flanged portion of the lower half of the twopart ring is provided at intervals with bearings K for the pintles I of the lids. These bearings are covered after the pintles have been seated therein by lips L,formed at intervals around the uppersection,L,of thetwo-part ring,whioh said lips fit and rest on the bearings K". The topsection of the two-part ring is also provided at intervals with inwardlyprojecting perforated ears 'L, arranged to register with similar ears, K with which the lower section of the two-part ring is provided. The bolts M pass through these perforated ears and through the lugs or ears A of the drum, thereby securely connecting together the two sections of the two-part ring, and also securing the latter upon the top of the drum.

The annular sections of the ring are preferably provided on their opposing faces with jacket, substantially as described.

, sion of the drum and of the annular corresponding shoulders, so as to adapt the parts to be more effectively'fitted together,'as in Figs. Blandv 6.
